1. Summary
Worldwide, extensive examinations concerning immobilization of hazardous waste have been performed, in order to contribute to the reduction of dumping capacity. We are talking about waste that has to be tipped costly with the necessary isolation, management and control facilities. The target that has to be set is to change waste materials as such, physical and chemical, that the risk of dispersal of environmental pollution through leaching, erosion and dispersion in the short and long term will decrease. Remnants that have to be considered are hazardous waste materials, due to their leaching behavior. The remnants have to be a substantial part of the solidified waste in relation to the additives and binders. For example, MWI fly ash is sometimes used as filler in asphalt. However, due to the low percentage of fly ash used, this processing of waste does not count as immobilization. Particularly cement-based immobilization, immobilization on the basis of bitumen and melt down has the attention. To a lesser extent, research has been performed on sintering of waste.
